18 LISHEP 2015, Manaus Development concluded in 2008 The PET Scanner with the best spacial resolution (1.3mm)The PET Scanner with the best spacial resolution (1.3mm) The only PET in the market with DOI measurement and without paralaxThe only PET in the market with DOI measurement and without paralax The highest density of integrationThe highest density of integration 3.0 mm 2.5 mm 2.0 mm 1.5 mm 1.2 mm SPACIAL RESOLUTION 18

19 LISHEP 2015, Manaus o We have fully developed two PET scanners o CLEAR PEM and CLEAR PEM SONIC o The validity of the results was demonstrated on clinical trails in Coimbra (Portugal) and in the Hopital Nord, in Marseilles (France) o We have identified several cases of cancers that were invisible in the full body PET scanners. o Still ongoing: o Clinical trials at Hospital San Gerardo, Monza, Italy o PET Markers studies (ICNAS, Coimbra) Clinical trials results 19

20 LISHEP 2015, Manaus Cancer cells are concentrated in the periphery of the tumor Small lesion in the left breast seen in PEM, but not in the whole body PET click for 3D animation Left Breast Right Breast Clinical Case : bilateral breast cancer

31 LISHEP 2015, Manaus 31 ENDOTOFPET project

32 LISHEP 2015, Manaus TOFPET microelectronics ASIC o Clock frequency 160 MHz o TDC time binning 50 ps o Power per channel 7 mW o SNR for single photoelectron 23.5 dB 64-channel chip design 64-channel silicon chip 128-channel dual-die BGA package IBM CMS 0.13  m o Benefiting from the experience with APDs, LIP and PETsys has developed microelectronics and detectors based on SiPMs. TOFPETASIC for Time of Flight PET

33 LISHEP 2015, Manaus Better time resolution will dramatically improve the PET image quality The accuracy of the source localization depends on the coincidence time resolution (CTR) ∆x= uncertainty in position along LOR = (speed of light) × CTR/2 The TOF benefit is proportional to D/∆x With PMTs CTR ≥ 500 ps if great care is taken to get the best CTR PETsys Detector Modules have CTR ~250 ps PET TOF
